What was possibly the gravest disaster of its class in this land of volcanoes, since the terrible eruptions which came in the twenty years ending in 1800, occurred in the Bandai-san region in northern Japan, on July 15, 1888. At about eight o’clock in the morning of that day, almost in the twinkling of an eye, Little Bandai-san was blown into the air, and wiped out of the map of Japan. A few moments later its debris had buried or devastated the surrounding country for miles, and a dozen or more of upland hamlets had been overwhelmed in the earthen deluge, or wrecked by other phenomena attending the outburst. Several hundreds of people had met with sudden and terrible death; scores of others had been injured; and the long roll of disaster included the destruction of horses and cattle, damming up of rivers, and laying waste of large tracts of rice-land and mulberry groves.
A small party was organized in Tokio to visit the scene. As the travelers approached the mountain, they were told that twenty miles in a straight line from Bandai-san no noise or earthquake was experienced on the 15th, but mist and gloom prevailed for about seven hours, the result of a shower of impalpable blue-gray ash, which fell to a depth of half an inch, and greatly puzzled the inhabitants. An ascent of about 3,000 feet was made to the back of the newly formed crater, so as to obtain a clear view of it and of the country which had been overwhelmed. Only on nearing the end of the ascent was the party again brought face to face with signs of the explosion. Here, besides the rain of fine, gray, ashen mud which had fallen on and still covered the ground and all vegetation, they came upon a number of freshly opened pits, evidently in some way the work of the volcano. Ascending the last steep rise to the ridge behind Little Bandai-san, signs of the great disaster grew in number and intensity.
The London Times correspondent, who was one of the party, wrote: “Fetid vapors swept over us, emanating from evil looking pools. Great trees, torn up by their roots, lay all around; and the whole face of the mountain wore the look of having been withered by some fierce and baleful blast. A few minutes further and we had gained the crest of the narrow ridge, and now, for the first time, looked forth upon the sight we had come to see. I hardly know which to pronounce the more astonishing, the prospect that now opened before our eyes or the suddenness with which it burst upon us. To the former no more fitting phrase, perhaps, can be applied than that of absolute, unredeemed desolation—so intense, so sad, and so bewildering that I despair of describing it adequately in detail.
“On our right, a little above us, rose the in-curved rear wall of what, eight days before, had been Sho-Bandai-san, a ragged, almost sheer cliff, falling, with scarce a break, to a depth of fully 600 feet. In front of the cliff everything had been blown away and scattered over the face of the country before it, in a roughly fan-shaped deposit of for the most part unknown depth—deep enough, however, to erase every landmark, and conceal every feature of the deluged area. At the foot of the cliff, clouds of suffocating steam rose ceaselessly and angrily, and with loud roaring, from two great fissures in the crater bed, and now and then assailed us with their hellish odor. To our eyes, the base, denuded by the explosion, seemed to cover a space of between three and four square miles. This, however, can only be rough conjecture. Equally vague must be all present attempts to determine the volume of the disrupted matter. Yet, if we assume, as a very moderate calculation, that the mean depth of the debris covering a buried area of thirty square miles is not less than fifteen feet, we find that the work achieved by this great mine of Nature’s firing was the upheaval and wide distribution of no fewer than 700,000,000 tons of earth, rocks, and other ponderous material. The real figure is probably very much greater.”
The desolation beyond the crater, and the mighty mass thrown out by the volcano which covered the earth, were almost incredible. “Down the slopes of Bandai-san, across the valley of the Nagase-gawa, choking up the river, and stretching beyond it to the foothills, five or six miles away, swept a vast, billowy sheet of ash-covered earth or mud, obliterating every foot of the erstwhile smiling landscape. Here and there the eyes rested on huge, disordered heaps of rocky debris, in the distance resembling nothing so much as the giant, concrete, black substructure of some modern breakwater. It was curious to see on the farther side the sharp line of demarkation between the brown sea of mud and the green forests on which it had encroached; or, again, the lakes formed in every tributary glen of the Nagase-gawa by the massive dams so suddenly raised against the passage of their stream waters. One lake was conspicuous among the rest. It was there that the Nagase-gawa itself had been arrested at its issue from a narrow pass by a monster barrier of disrupted matter thrown right across its course. Neither living thing nor any sign of life could be discerned over the whole expanse. All was dismally silent and solitary. Beneath it, however, lay half a score of hamlets, and hundreds of corpses of men, women and children, who had been overtaken by swift and painful deaths.”
Although the little village of Nagasaka was comparatively uninjured, nearly all its able-bodied inhabitants lost their lives in a manner which shows the extraordinary speed with which the mud-stream flowed. When Little Bandai-san blew up, and hot ashes and sand began to fall, the young and strong fled panic-stricken across the fields, making for the opposite hills by paths well known to all. A minute later came a thick darkness, as of midnight. Blinded by this, and dazed by the falling debris and other horrors of the scene, their steps, probably also their senses, failed them. And before the light returned every soul was caught by a swift bore of soft mud, which, rushing down the valley bed, overwhelmed them in a fate more horrible and not less sudden than that of Pharaoh and his host. None escaped save those who stayed at home—mostly the old and very young.
A terrible earthquake convulsed central Japan on the morning of October 25, 1891. The waves of disturbance traversed thirty-one provinces, over which the earth’s crust was violently shaken for ten minutes together, while slighter shocks were felt for a distance of 400 miles to the north, and traveled under the sea a like distance, making themselves felt in a neighboring island. In Tokio itself, though 170 miles from the center of disturbance, it produced an earthquake greater than any felt for nearly forty years, lasting twelve minutes. Owing, however, to the character of the movement, which was a comparatively slow oscillation, the damage was confined to the wrecking of some roofs and chimneys. Very different were its results in the central zone of agitation, concerning which a correspondent wrote as follows:
“There was a noise as of underground artillery, a shake, a second shake, and in less than thirty seconds the Nagoya-Gifu plain, covering an area of 1,200 square miles, became a sea of waves, more than 40,000 houses fell, and thousands of people lost their lives. The sequence of events was approximately as follows: To commence at Tokio, the capital, which is some 200 miles from the scene of the disaster, on October 25th, very early in the morning, the inhabitants were alarmed by a long, easy swaying of the ground, and many sought refuge outside their doors. There were no shocks, but the ground moved back and forth, swung round, and rose and fell with the easy, gentle motion of a raft upon an ocean swell. Many became dizzy, and some were seized with nausea.”
These indications, together with the movements of the seismographs, denoted a disturbance at a considerable distance, but the first surmise that it was located under the Pacific Ocean, was unfortunately incorrect. The scene of the catastrophe was indicated only by tidings from its outskirts, as all direct news was cut off by the interruption of railway and telegraphic communication. An exploratory and relief party started on the second day from Tokio, not knowing how far they would be able to proceed by train, and the correspondent who accompanied them thus described his experiences:
“Leaving Tokio by a night train, early next morning we were at Hamamatsu, 137 miles distant from Tokio, on the outside edge of the destructive area. Here, although the motion had been sufficiently severe to destroy some small warehouses, to displace the posts supporting the heavy roof of a temple, and to ruffle a few tiles along the eaves of the houses, nothing serious had occurred. At one point, owing to the lateral spreading of an embankment, there had been a slight sinkage of the line, and we had to proceed with caution. Crossing the entrance to the beautiful lake of Hamana Ko, which tradition says was joined to the sea by the breaking of a sand-spit by the sea waves accompanying an earthquake in 1498, we rose from the rice fields and passed over a country of hill and rock. Further along the line signs of violent movement became more numerous. Huge stone lanterns at the entrances of temples had been rotated or overturned, roofs had lost their tiles, especially along the ridge, sinkages in the line became numerous, and although there was yet another rock barrier between us and the plain of great destruction, it was evident that we were in an area where earth movements had been violent.”
